Application February 26, 1934, Serial No. 713,037 I 1 Claim.

This invention relates to clamps and has as its object the provision of a clamp for supporting and securing a hand saw in position to facilitate the filing of the saw.

An object of the invention is to provide a clamp of this character which may be readily and detachably mounted on one end of a work bench and which will positively secure a hand saw, or a saw blade of any known description in position to facilitate the filing of the teeth of the saw.

A still further object of the invention is to provide a clamp of this character consisting of relatively few parts and which can be economically constructed and sold for a nominal price.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure l is a top plan view illustrating the application of the clamp.

Figure 2 is a side elevational view thereof.

Figure 3 is a sectional view taken substantially on the line 3-3 of Figure 2.

Figure 4 is an elevational view of one end of the clamp.

Figure 5 is an elevational view of an opposite end of the clamp.

Figure 6 is a perspective view of one of the members of the clamp.

Figure 7 is a perspective view of the other member of the clamp, and

Figure 8 is a fragmentary detail sectional view illustrating certain details to be hereinafter more fully pointed out.

Referring to the drawings by reference numerals it will be seen that the clamp comprises two cooperating clamp members I0, II each of which is formed of angle iron and has a portion thereof at one end extended and rolled upon itself to provide a hinge eye I2. Secured 'to the hinge eye I2 of the clamp member I0 is a hinge pin I3 with which is engaged the hinge eye I2 of the clamp member I I for hingedly connecting the members. At the free end thereof the clamp member ID is tapered as at I4 and is rolled upon itself to provide a spring clip or catch member I5 with which the free end of the clamp member I I is engageable for securing the clamp members II), II in clamping relation with the blade of a saw or the like clamped therebetween.

The flange Illa of the clamp member ID is adapted to overlie a work bench or other suitable support I8, and at the end thereof the flange I (la is provided with anchoring prongs I I that are adapted to be embedded in the top of the table or bench I6 in the manner suggested in Figures 4 and 5 for securing the clamp to the table. The prongs H are formed in any suitable manner,

preferably by slitting the flange I0 and bending a portion of the flange adjacent the slit at right angles to the body of the flange, and then shaping these bent portions to points.

For suitably spacing the clamp member I0 from the end edge of the bench I6 said member ID on one side thereof is provided with fixedlugs or projections I8 that are adapted to be placed against the end edge of the bench It in a manner clearly shown in Figure 5.

At the hinged end thereof the clamp member II has its vertical flange tapered or beveled as at I9 to accommodate the handle 20 of the saw when the blade 2! of the saw isclamped between the members I0 and II as will be clear from a study of Figure 2.

In actual practice the clamp is secured to one end of the work bench I6 in the manner herein- 7 before described in detail; the blade .2I of the saw is placed between the clamp members IE], I l

with the handle 20 disposed at the hingedly connected ends of the clamp members and will be secured between the clamp members when the clamp member II is swung from the dotted line position shown in Figure 1 to the full line position shown in Figures 2 and 3 and the free end edge of the member I I engaged with the spring keeper I5 of the stationary clamp member. It will be apparent that with the saw thus secured by the clamp the toothed edge thereof is disposed upwardly and the arrangement is such that a filing of the teeth can be readily and quickly accomplished.

It will be further understood that in actual practice the eye I2 will be of a length sufiicient to permit vertical or up and down movement of the clamp member I I with suflicient freedom so as not to bend the hinge pin l3.

Having thus described my invention, what I claim as new is:

In a saw clamp, a pair of jaws hingedly connected together at one end and provided at the end thereof opposite to the hinge with inter-engaging means for releasably securing the jaws in substantial parallel clamping position, said jaws being constructed of angle iron to provide vertically disposed parallel flanges and a horizontal flange at the upper edge of each vertical flange projecting respectively in an opposite direction, and the horizontal flange of one of said jaws having pressed therefrom penetrating prongs for piercing engagement with a support, and the vertical flange of said one jaw being also provided with spaced lugs to engage an edge of the support for spacing the vertical flanges of the jaw from said edge of the support.

ALBERT DAWSON.
